To ciZZivZzbm it mm 7 t Be it known that WGLGEZAQ GREENBEBG and K TSToYE, both citizens 071: theUnit-ed' Stat-es, residing, respectively,at NevvYprk city, county of Ne'W York, State of New York, and Flushing,Long Island, county of Queens, State of New York, have invented certainnew and useful Improvements in" a Urethroscope, of which the followingis a specification. I I

This'invent-ion relates to an improvement in a urethroscope and thenovelty consists in theadaptation and arrangement of :arts as will bemore fully hereinafter pointed out. This device is particularly animprove ment of the urethroscope of Greenberg & WVinter described andclaimed in United States Letters Patent No. 1,453,)75, or May 1, 1923',and reference ma be made to that patent to cover the general operationof urethroscopes, p v I Great difiiculty has been found in' the use ofurethroscopes in lookinginto the bladder ccvity or other cavity to beexamined be 2 cause of the lack of an adjustable telescope whichdifiiculty our device has o veiceme y combining with a urethroscope acollapsible telescope Which can he swung into position for use when.desired or swung out of positionso as to be out of the ay as may berequired, and also be detachabl'y reinoved Anotherhandicap in the use ofurethroscopes hasheen in the failure to eliminate bubbles occi lrriligin the Water which is used to inflate the! organ to be examined, andwhich obstruct the vision of the o erator. Our device has overcome thisdifficulty and furnishes-means lofre'ady eliliiination of such bubblesWithout disturbing the" m-euuescope and other instruments therein duringthe operation; a

Our device also furnishes an eccentiiic coupling thereby permitting theuse of va rious sizes of tubes Withoutlosing the aline- 4 ment necessaryfor sighting through the eye piece of the urethrosoope.

Or device also furnishes a more perfect connection for the lightingIneans so" as to secure perfect contact under all conditions, and alsoembodies a: sliding depth" gauge which enables the operator todefinitely deterinine the depth of the insertion of the urethros copeand a; aefinituy eer-min are exact amount it must emevea where achange'yis required. 6 e Referring to the drawings, Fig. 1 is a top planview of our improved urethroscope which has been broken for conveniencein illustration, and Whichshmvs the collapsible telescope svg' uiig outOf IP OSltlO'Il, as whee not in use, and showing itiii position for usein dotted outline; a

8 is a urethral, tube to vvhichli's secured an eccentriccoup-ling9,:i11'd a'inain body 10 of our device isadapted.to 'be rigidly securedto said couplingf) in which there is a water inlet 11 having a valve ,12controlling the same; Eye piece 13 is also rigidly mounted .in the body10 and" has tlie usual lens 14. In eyepiece 13 there is alsohioimted inflange 156a set screw 16 of usual construction and which is adapted toserve as an one let for air bubbles forin-ing tiiivspace 617 on 1 theinside ofth'e lens 14. A collapsible telescope 118' of usualconstruction is r'nou'nted 0 11 the body 10 by means of a bracket 19which is removahly' secured to a screw clamp 20, the has efo'fwhich isiiiteg-ral With the bpdy' 10. A sliding depurgaugeei ismou'iitd' on thetube sand has. a slot 22 permitting the operatorjito see divisionalmarks 23 on the tube '8 so, that the sliding 9x11516521 can he movedto'th'e exact position vv'hih is to locate it "so as to serve; as adepth] gauge for the insertion of the tube 8. Through the base or thebody 10 a lightingvvire 24 of usual cons'truotion is adapted to bemounted so" as to pass through a lighting tube 25" which is adapted tolie along the haseof the inside of the tube lighting tubeiQZB termina'tesin an internal threetdingfiti into which is adapted to he threaded acbiitain merriper 27 having an opening 28 and in which or AMEmcA, or newYORK,

opening 32 in the opposite end of the con tainer member 27 from theopening 28. A lamp 33 of usual construction having a threaded socket 34is adapted to be mounted in the internal threading 26 until a contactnipple 35 at the base of said socket34 is registered in contact with thesliding member 32. This construction assures the contact of the wire .24with the plate 29 and through the spring and sliding member 31 alwaysensures contact with the contact nipple 35 in spite of variationswhichmight otherwise break the contact were it not for the sliding member '32which under spring pressure 30 will always ride up into contact with theco-ntactnipple 35, thus assuring a light during the entire operation andeliminating the possibility of the failure of the light through thebreaking of the contact.

The eccentric nipple 9 has a boring 36 which is eccentric so as toassure the alinement of the lens 14' and telescope 18 so that the visionof the operator will always be clear through the tube 8 and so thatthelighting tube 25 will always lie at the base out of the way ofpossibility of obstructing the vision of the operator. A larger tube isnoted in dottedoutline as 37in Fig. 4 thus always assuring the largestpossible amount of unobstructed space through the tube 8 .for'the visionof the operator. i

Figs. 6 and 7 show further modifications 'or alternativeforms for theair outlet in which, as is shown in Fig. 6, a nipple 38 has an internalthreading 39 adapted to screw into an internally mounted boring 40 intheeye piece 13, said nipple 38 having an internal threading 41 in whichthe screw 42 is adapted to be seated so as to control the outlet 43 inthe nipple '38.. Fig. 7 shows a springv valve member having a base 44adapted to be rigidly mounted in the eye piece 13' having a valve seat45 in which a valve 46 is adapted normally to seat under pressure ofspring 47 said base 44having an outlet 48 so that air or bubbles formedin chamber 1 7 may pass out through said valve 44 when it is open,orthrough Valve 42 when it is open, or throughvalve 16 when it is 'open,these three being alternative forms of valves. In using this device thetube 8 will be inserted into the'urethra in the usual way and thebladder will then be distended by turning on the water ininlet 11, whichis controlled by valve 12, until the bladder is suificiently distended.The operator can then swing thetelescope 18 into position for 1observationand the light 33 will illuminate 'the cavity being examinedso that the operator can use the instrument desired upon removing eyepiece 13 and if the telescope 18 is in the way it can be swung to oneside temporarily or it can be readily removed. The light 33 will notflicker and vary because of imperfect contact but will burn steadily asthe contact will always be maintained steadily'by the sliding member-31which insures a positive perfect contact in spite of any variation whichmay be caused by jars or movement of parts. Also by opening air pressurevalves 16, 42 or 44 which can be easily and quickly done by the operatorwithout disturbing the operation, all bubbles gathering on the inside oflens 14 may be eliminated thereby assuring a clear vision at all times.

It "will be understood that although this device is called aurethroscope, it is also adapted to be used in the other natural bodyopenings and the use of such na meis not intended to in any way limitthe scope of the invention.

We claim:

1. In a urethroscope, the combination of ably attached to the body ofsaid urethroscope and a sliding depth gauge mounted on said tube.

2. In a urethroscope, the combination of a urethral tube having anexternal scale thereon, an eccentric coupling, an eyepiece, 1 i

3. In a urethroscope adapted ,for water inflation of the organ to beexamined, a tube having an external scale thereon and a sliding depthgauge mounted on said tube, a collapsible telescope secured to thebody'of said urethroscope so that it can be readily swung into or out ofposition for use and be readily removed therefrom and means for lightingthe distal end of said tube.

4. In a urethroscope, the combination of a urethral tube] having anexternal scale thereon, an eccentric coupling, an eyepiece, a waterinlet, an air outlet valve, a collapsible telescope removably andadjustably attached to the body of said urethroscope and a sliding depthgauge mounted on said tube, and means for lighting the distal end ofsaid tube comprising a bulb connected to the power wire by a slidablemember under inflation of the organ to be examined, a tube having anexternal scale thereon and a slidmg depth gauge mountedon sald tube, a
